## Round The Table

### Swathi

* German ESPPU meeting in Hamburg, interesting presentations and broad discussions

* PandoraPFA callibration 
    * Only use Version 1 of the LAr Ecal Barrel
    * Use constant layer radius, still showing multiple peaks
    * Draw energy deposit per layer
        * What is drawn? Energy deposit? Energy deposit per sensitive thickness? ...?

* Submitted ICHEP poster proceedings to CDS (also accepted by conference already)
* Other paper is now being reviewed

### Andre

* NTR

### Juan

* Continued investigation of ACTS tracking
    * Used example chain from ACTS, but seeds are not being used to pick up more hits for OpenDataDetector
        * DDplanarDigi then seeding in ACTS and tracking, gives only 3 hit tracks
        * Vs. Digi in ACTS then seeding in ACTS and then tracking, gives tracks
    * ACTS still very unstable
        * Create Measurement broke

* Options for vector members
    * https://github.com/key4hep/k4FWCore/issues/260
    * Issue in GaudiProperties in combination with Functional algorithms?

* podio with c++20
    * https://github.com/AIDASoft/podio/pull/698
    
### Mateusz

* root hackathon
* podio interfaces across multiple datamodels
* julia jet reconstruction compilation
    * Reviewing Graeme's PR about using different floating points
        * Bug in julia?
            * Non-parametrized outer constructor and parametrized outer constructor on floating point type, julia complains one function overwrites the other
* reviewing Oleksandr Shchur's thesis plan
